One of the new sheet metal enhancement in Inventor 2011 is the ability to associatively copy a model sketch into the flat pattern environment. this could be useful if you have things like score lines you want to layout on the model, and should transfer into the flat pattern as well. Let’s take a look at the procedure:
- Create a new unconsumed sketch in the sheetmetal model. Don’t worry about color or linetypes yet, but change any non-relevant geometry to construction if you like.
- Right click on the model sketch and pick “Copy to Flat Pattern”.
- Enter the flat pattern environment and edit the properties (color, linetype, lineweight) of the copied sketch geometry.
- Save the flat pattern as a DWG, DXF, or SAT file and it will include the copied sketch geometry as well.
This can save a lot of unneeded flat pattern cleanup that might otherwise be required before programming CNC code off the flat.
